This invention relates to adjustable covers and more specifically is directed to an adjustable weather-proof cover particularly adapted for use in protecting a central air conditioner compressor cabinet or the like against the elements and other foreign matter.
Central air conditioning has become prevalent in many private residences. In multi-seasonal climates where it is only used for one season of the year, the externally disposed compressor cabinet and associated equipment housed within are not used during the other seasons. When inoperative, there is a tendency for dust, dirt and the like to collect within the compressor cabinet, thereby having a deleterious effect on the static and dynamic parts. Moreover, the sheet metal cabinet housing the working parts serves to amplify the sound of rain, sleet, snow or hail with the expected disturbing effect on the occupants of the premises. In the past, custom made covers have been used to protect compressor cabinets against the elements during periods of non-use, however these covers are extremely expensive when compared to those which are mass produced to a uniform size.
A wide variety of air conditioners are available and considerable variance exists in the size of the compressor cabinets for different sizes and competitive models. Accordingly, any cover which may be provided for protecting the compressor cabinets over the periods of non-use must be adjustable in order to accommodate most models and types if the benefits of mass production are to be obtained.
Consequently, there is a need for a universal air conditioner which is economical to produce, easy to install and is dependable.
The present invention relates to a cover which may be used for air conditioner compressor cabinets or the like, and which is readily installed to protect the cabinet and working parts housed therein. The adjustable cover of the present invention through an ingenious arrangement of elastic bands and strategically placed fasteners is adjustable to fit a wide range of cabinet sizes and is easily installed by an unskilled person. As will be seen, the adjustable cover of the present invention is formed of one sheet of material to cover a compressor cabinet and present an attractive appearance while precluding cabinet deterioration and entry of foreign matter into the interior of the cabinet.
It is an object of this invention to provide a one-piece adjustable cover adapted for use in covering air conditioner cabinets and the like.
It is a further object of this invention to provide a new and improved air conditioner cabinet cover which is adjustable over wide ranges of sizes.
It is a still further object of this invention to provide an adjustable air conditioner cover which will fit a wide range of units, which is easily installed, will remain firmly in place once installed, and present a neat appearance.
Other objects, advantages, and novel features of the present invention will become apparent from the following detailed description of the invention when considered in conjunction with the accompanying drawings.

FIG. 10 is a view like FIG. 9 but showing one side being fastened in place;
FIG. 11 is a view like FIGS. 9 and 10 but showing the left-most flap folded and fastened into place to complete the installation of the central air conditioner cover apparatus;
FIG. 12 is a perspective view of the present invention shown installed on a central air conditioner housing on the opposite side from the perspective view of FIG. 5;
FIG. 13 is a cross-sectional view taken along line 13--13 of FIG. 11; and;
FIG. 14 is an enlarged partial cross-sectional view taken along line 14--14 of FIG. 11.
Referring now to the drawings wherein like reference numerals designate identical or corresponding parts throughout the several views, FIG. 1 shows a central air conditioner cover apparatus constructed in accordance with the present invention and being formed of a flexible canvas sheet (25). It is to be understood, of course, that other types of flexible material can be used, such as another fabric or a sheet of plastic.
A central air conditioning housing (26) is shown in FIG. 2 mounted on a concrete slab (27). To install the cover (1) to the central air conditioner housing (26), it would first be draped over the top of such air conditioner cabinet (26) in a position so that the fluid conduit pipes (28 and 29) extend past a slit (17), which extends from a first edge (30) of the sheet (25) to a place inwardly therefrom. The flap (18) is then folded into a triangle along the dash line (31) so as to provide an opening for fluid conduit pipes (28 and 29). Alternatively, the triangular flap (18) can be cut out entirely from the sheet (25), thereby leaving a void where the flap (18) is indicated. Another slit along the dash line (23) can also be cut, if it is required because of the configuration of pipes or conduits such as fluid conduits (28 and 29). A first fastener (8) is attached to a first corner of the sheet and a second fastener (9) is attached to the second corner of the sheet. For the purpose of this illustration, the first and second fasteners include the button and female portion of a snap. Fasteners (10, 11, 12, 13, 14, 15, and 16) are also of the type like fastener (8) which has a female portion for receiving and holding a male snap portion. Male snap fasteners (5, 6, 7, 19, 20, 21, and 22) are of the type shown in FIG. 6 as projection 22.
Elastic members (2), (3) and (4) are sewn to the sheet (25) along the slit (17) as can readily be seen in FIG. 1.
After the cover (1) is draped over the air conditioner housing (26) then the corners pleated as shown in FIG. 2. The snap fastener (8) is snapped over the male fastener (22) so that the apparatus is in position shown in FIG. 3. At the same time, the first, second and third elastic members (4, 3 and 2) are stretched across the slit (17) to engage fasteners (7, 6 and 5) respectively. This holds the cover securely around the pipes (28) and (29). Then the other flap shown in FIG. 3, having fastener (9) thereon, is folded over to the position shown in FIG. 4 and the fastener (9) is fastened together with the male fastener (21). This can readily be seen in FIG. 7. Consequently, one end of the cover (1) will be secured in place, as is readily shown in the perspective view of FIG. 5 with the fluid conduits (28) and (29) extending therethrough.
The other end of the cover (1) would then be placed in the position shown in FIG. 9 wherein two of the corners are folded apart. Then the right side, as shown in FIG. 9, is folded over to the position shown in FIG. 10, exposing fasteners (11, 12 and 13) and also allowing access to the male snap (20). The left flap, as shown in FIG. 10, is then folded over so as to connect fastener (10) with the male fastener (20), as shown in FIG. 14, and also engaging the fastener (19) with one of the three fasteners (11, 12 or 13), depending upon the degree of tightness desired due to the size of the air conditioner housing (26). The completed end of the cover (1) is shown in FIGS. 11 and 12.
It is also to be understood that other types of fasteners can be used instead of snaps. For example, referring to FIG. 1, it is noted that the dark-colored female fasteners like fastener (8) could be of one complementary part of a Velcro fastener and the light-colored fasteners such as (22) could be of another complementary Velcro component so that the numbered fasteners can be attached together with Velcro instead of with snaps.
Accordingly, it will be appreciated that the preferred embodiment disclosed herein does indeed accomplish the aforementioned objects. Obviously, many modifications and variations of the present invention are possible in light of the above teachings. It is, therefore, to be understood that, within the scope of the appended claim, the invention may be practiced otherwise than as specifically described.
